Eco Factor: Sustainable skyscraper designed to harvest rainwater. Architectural students of H3AR have received a special mention for their proposal in the 2010 skyscraper competition, for a sustainable skyscraper that maximizes rainwater harvesting. Dubbed Capture The Rain, the skyscraper features an innovative roof and external shell, which consists of a system of gutters to harvest rainwater to meet the daily needs of its inhabitants. The designers estimate that the average daily consumption of water per person is about 150 liters, out of which 85 liters may be replaced by rainwater. The design team focused on the shape of the roof to capture as much rainwater

as possible. Under the roof’s surface, special water reservoirs have been placed in the form of a large funnel and reed fields, which serve as a hydro botanic water treatment unit. This unit processes water to make it usable before it is transmitted to apartments. A network of gutters on the external surface of the building is designed to capture rainfall flowing down the building. While most of the harvested water is supplied to the apartments, surplus water is stored in a reservoir under the building. Via: DesignBoom
